to machines for mountcation of John W. Pratt. It is a common practice tobegin the manufacture of such a shoe by asse'mbling'and stitchingtogether a shoe upper, a sock lining, and a platform cover and then tomount this assembly, which constitutes a partially completed shoe, upona last for the purpose of imparting to it a desired shape and also forfacilitating the performance of subsequent oper ations. The partiallycompleted shoe is mounted upon the last first by placing it loosely uponthe last and then by urging it rearwardly on the last with considerableforce. This operation, which is analogous to the relasting of turnedshoes or of McKay or Littleway shoes, is commonly known as forcelastingor slip lasting.

It is an object of the present invention to provide a simple andinexpensive machine for In accordance with this object, the machinedisclosed herein is provided with means engageable with the last onwhich the shoe is mounted, means engageable with the platform cover, andmeans for exerting a force between the two first-mentioned means toeffect relative movement between the last and the shoe. As shown herein,the means engageable with the platform cover fits into the heel end ofthe open pocket formed by the platform cover, and the force is directedheelwardly to urge the shoe further on the last. This means mayconveniently consist of a block which is slidable forwardly andrearwardly on the sock lining and which has its rear portion shaped tothe outline of the heel end of a shoe to enable it to engage the heelend of the pocket formed by the platform cover.

These and other novel features of the invention are illustrated in theaccompanying drawings and hereinafter described and claimed.

Referring to the drawings,

Fig. 1 is a side elevation of an illustrative machine embodying theinvention, the movable parts of the machine being shown in the positionswhich they occupy at the beginning of an operation;

Fig. 2 is a view similar to Fig. 1 showing the positions of the movableparts of the machine at the completion of an operation; and

Fig. 3 is a plan view of a block constituting a portion of the machineshown in Figs. 1 and 2.

The work-engaging instrumentalities ,of the illustrated machine consistof an upstandingstationary last pin 10 and a movable block 12. The lastpin l0, which supports in inverted position a last L, is secured uponthe top of a short standard 14 fixed upon a work bench IS. A partiallycompleted shoe consisting of an upper U, a sock lining S, and a platformcover Chas been loosely mounted upon the last L by hand. .The platformcover C has already been turned to extend away from the last and to forman open pocket with the sock lining S. p

The block [2, as shown in Fig. 3, has a rear portion l8 shaped to theoutline of the heel end of a shoe to enable it to engage, over asubstantial area, theinterior of the heel end of the platform cover C.The forward portion of the bottom of this block may conveniently bebeveled as indicated by the reference numeral 20.

The operating instrumentalities of the block l2 comprise a treadle 22fulcrumed upon a stationary pin 24 mounted in a bracket 26 secured tothe floor. A rod 28 pivotally connected atits lower end to the treadle22 and at its upper end to one arm of a bell crank 30 transmits motionfrom the treadle to the bell crank. The bell crank Si] is fulcrumed upona stationary pin 32 carried by a bracket 34 secured upon the work bench[6. The other arm of the bell crank 30 extends upwardly and carries apivot pin 36 upon which is mounted for heightwise swinging movement oneend of a short link 38, the pin 36 being approximately on a level withthe turned platform cover C. Pivotally connected to the other end of thelink 38 by a pin 40 for swinging movement laterally of the shoe is oneend of a bar 42. The link 38 and the pins 36 and 40 thus constitute auniversal pivot. The other end of the bar 42 is rigidly secured byscrews 44 to the upper surface of the block l2. A spring 46 normallyholds the treadle 22 in raised position as shown in Fig. 1. Adjustabletreadle stops 48 and 50 are provided to prevent excessive movement ineither direction.

The operation of the above-described machine upon the partiallycompleted shoe will now be explained. The operator moves the block l2laterally or heightwise (or both) to an out-of-the- Way position andthen loosely mounts the partially completed shoe by hand upon the lastL, preferably after placing the last upon the last pin l 0, and hemanipulates the shoe to draw it as far rearwardly on the last as heconveniently can by hand. He then replaces the block i2 in its operativeposition and depresses the treadle 22,

causing the block l2, which rests by its own weight on the sock liningS, to slide rearwardly into engagement with the interior of the rear endof the pocket formed by the platform cover The block 12, being free toswing about the pin 40, will automatically adjust itself laterally ofthe shoe. Further downward pressure upon the treadle 22 causes the block12 to exert positively a considerable rearward force,which'issubstantially hori-- zontal or lengthwise of the shoe, upontheiplatform cover and therefore the sock lining. thus urging the shoefurther upon the last, from the position shown in Fig. 1 to that shownin Fig. 2. While depressing the treadle the operator may, if desired,use both hands to assist in urging the forepart of the shoe into properrelation to the last and smooth it thereagainst. After the shoe has beendrawn rearwardly by the treadle mechanism as far as desired, with theheel end of the -sock lining in register with .the heel end of the"Iast, the operator may turn the heel end of the upstanding platformcover down around the heel endof the last to prevent undesirablecontraction {of the sock lining and creeping of the heel end of the shoeforward of the heel end of the last.

The shoe shown in the drawings may be provided with a heel strap Hwhich, if provision is jmade iorbuck-ling'it, may conveniently be leftunibuckled. In shoes having continuous heel straps with no provision forbuckling, it is often convenient to draw the heel strap over the .heelof the last by hand; but if the heel strap is too tight, it may beraised above the last. Likewise, shoes having continuous heel slingsinplace of the strap H and secured only to the sock lining S may,

too tight, beraised in a similar manner.

Having described myinvention, what I claim as new and desire to secureby LettersPatent of the United States is:

;1. In a force lasting machine, a support for an inverted last on whichis loosely mounted a partially completed shoe having .a platform coverturned right side out to form an .open pocket, a member shaped to theoutline of the heel end of a shoe and having a working surface whichextends heightwise of the shoe and which is engageable with the interiorsurface of the open pocket, and means for exerting between the lastsupport and the pocket-engageable member a horizontal heelwardlydirected. force to urge the shoe heelwardly on the last.

.2. A force lasting machine comprising an upstanding last pin forsupporting in inverted position a last on which is loosely mounted apartially completedshoe having a platform cover stitched to its socklining and turned away from the last tonform a pocket at the heelportion, a block slid- .able .torwardly and rearwardly on the socklining and engageable, when slid rearwardly, with the pocket at the heelend of the shoe, said block having its rear portion shaped to theoutline of the heel end of a shoe, an arm secured to said block andextending rearwardly therefrom, means constituting a universal pivotconnected to the rear end of said arm and about which the arm and theblock are free to swing heightwise and laterally, and treadle operatedmechanism connected to said universal pivot whereby the block can heslid rearwardly into engagement Withthe pocket of the platform cover andpressed rearwardly against the pocket to urge the shoe further on thelast CECIL HOWARD FREER.
